The watch has a 42-mm-diameter stainless steel case, with both satin-finished and polished surfaces. The names of 24 world cities are printed on the outer periphery of the dial; inside this ring is a 24-hour scale with Arabic numerals, and inside that one is a 12-hour scale with Roman numerals. There are two different dial executions, one for Europe and the other for Asia, with their respective continents engraved in the dial’s center. The European dial features guilloché work with a Clous de Paris motif. The outlines of the silhouetted continent are in blue, matching the blued hands and hour-markers. The Asian version has a silvered dial, with a sun-brushed, satin finish on the engraved continent along with an opaline treatment on the oceans. This model uses rose gold for its numerals and hour and minute hands and has a blued seconds hand.
Both versions of the Maurice Lacroix Masterpiece Worldtimer have day/night indication on a subdial at 9 o’clock and the date on a subdial at 6 o’clock. The central 24-hour hand (rose gold on the European dial, black gold on the Asian) indicates the time in your home time zone on the 24-hour scale. To change the current time on the main dial, a traveler simply presses the push-button on the side of the case, which advances the 12-hour hand.
The movement in the watch is Maurice Lacroix’s self-winding Caliber ML164, which has a power reserve of 40 hours and features numerous decorative touches, including circular graining and côtes de Genève on the wheels and bridges, and côtes de Genève on the gold-plated rotor. Both versions of the Maurice Lacroix Masterpiece Worldtimer are available on black (Europe) or brown (Asia) crocodile leather straps or a polished and brushed steel link bracelet. All four executions of the watch, all priced at a rather modest $4,800, are pictured below; photos can be enlarged with a click. Detailed specs of the watch are below the photos.
